Who Needs Antivirus Software?

These days, everybody needs antivirus software.

Computer viruses don’t just come from streaming or downloading movies. Many people think that they can avoid potential threats by making sure they don’t visit certain websites or download certain files.

The truth is computer viruses can make their way onto your computer or any other device in a number of ways. You can pick up viruses and malware simply by checking your email, browsing the web or from putting a USB memory stick into your laptop.

Virus protection is a requisite of having your own personal computer. Luckily for you, there are hundreds of choices of antivirus software – each with its pros and cons. Making a choice between internet security software can be difficult, but that’s what we’re here for!

How Antivirus Works

Most antivirus software works on a signature database, monitoring the internet 24 hours a day, 7 days a week. Every time a new virus is reported – it’s indexed, catalogued and added to the software’s database. Once your antivirus software is up-to-date it is equipped to tackle the new virus should it ever reach your device.

How to Handle Viruses

You often have three options when faced with a threat on your computer: delete the threat, quarantine it or ignore it.

Deleting is almost always the best option, but some viruses make themselves "un-deletable" and quarantining becomes your only option. Your quarantine folder will keep the virus isolated and prevent it from spreading or causing damage to other files. Antivirus software can be passive or active – passive requires you to make scheduled or manual virus scans, while active runs in the background; detecting and fighting threats in real-time.

Free vs Paid Antivirus Software

If you are deciding on a new antivirus software and may want to try a free version, keep in mind that there are pros and cons for both paid and free versions. Using a free antivirus software can cost you more in the long run and most experts suggest that it’s better to use a paid version. Free versions can be great to try a new software or set of features, but will never provide the same level of protection - and your service most certainly won’t include internet security software.

Paid versions of antivirus software will cover both online and offline activities, permanently delete sensitive digital files and provide extra encryption to protect your most private files from malware like Trojans, worms and ransomware.

A paid antivirus software is especially helpful if you have a PC or device that has already been infected. Many paid versions offer virus removal and cleanup tools, in addition to the highest-quality prevention and detection rates.

Extra Features

There are a few key features that you should look out for when looking for antivirus software, and it will vary depending on your needs.

Online Protection - If you’re online, then you probably want an internet security software with a built-in firewall.

Email Protection - If you’re a heavy email user then you’ll want be on the lookout for anti-spam, spyware and phishing.

Parental Controls - Parents need to look for software with easy-to-use parental controls and restrictions.

Gaming Protection - Gamers can look forward to a "gaming mode," which prompts the internet security software to use less resources.

Compatibility - You will want to check the compatibility of your chosen software with your operating system, whether that be Windows protection, Mac OS antivirus and everything in between.
